[0021] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 4 The present application will be further described in detail.

[0022] The embodiment of the present application discloses an AGV lifting frame.

[0023] The AGV lifting frame is partially arranged on the ground and partially arranged in the underground parking lot. The AGV lifting frame comprises a parking house 1 and a lifting frame 2. The parking house 1 is arranged on the ground, the upper half of the lifting frame 2 is arranged in the parking house 1, and the lower half penetrates the ground and is located in the underground parking lot. The lifting frame 2 is further provided with a driving member 22. The lifting frame 2 is provided with a lifting platform 21. The driving member 22 is in transmission connection with the lifting platform 21. In the present application, the driving member 22 and the lifting platform 21 are in screw rod transmission. In other embodiments, the driving member 22 and the lifting platform 21 can also be in cylinder transmission. Specifically, the lifting platform 21 can be lifted and lowered, and the transmission mode is prior art, so it is not described in detail.

[0024] The lifting platform 21 is detachably provided with a vehicle support plate 3. The vehicle support plate 3 is provided with a tire limiting assembly 4. An AGV transfer vehicle 11 is further arranged in the underground parking lot. After the automobile is driven onto the vehicle support plate 3, the tire limiting assembly 4 limits the automobile tire, and then the driving member 22 lowers the lifting platform 21 to lower the automobile to the underground parking lot. The AGV transfer vehicle 11 can transfer the automobile to the parking point in the underground parking lot together with the vehicle support plate 3. The AGV transfer vehicle 11 is prior art, and is not described in detail.

[0025] The tire limiting assembly 4 comprises a pushing block 41, a pushing groove 42, a limiting groove 43, a tire limiting plate 44, and a limiting spring 45. The vehicle support plate 3 is placed on the lifting platform 21, the pushing block 41 is fixed on the lifting platform 21, and the pushing groove 42 is arranged on the vehicle support plate 3 and communicates with the limiting groove 43. After the vehicle support plate 3 is placed on the lifting platform 21, the pushing block 41 enters the pushing groove 42. The tire limiting plate 44 is rotatably arranged in the limiting groove 43, and the limiting spring 45 is fixed in the limiting groove 43 and abuts against the tire limiting plate 44 and has a tendency to push the tire limiting plate 44 to expose the surface of the vehicle support plate 3. The pushing block 41 can push the tire limiting plate 44 to reset in the limiting groove 43. When the AGV transfer vehicle 11 pushes the vehicle support plate 3 to separate the vehicle support plate 3 from the lifting platform 21, the pushing block 41 moves away from the tire limiting plate 44, and the limiting spring 45 pushes the tire limiting plate 44 to make the tire limiting plate 44 expose the upper surface of the vehicle support plate 3. The tire limiting plate 44 is located on the front and rear sides of the tire, and when the vehicle moves, the tire limiting plate 44 can abut against the tire of the vehicle.

[0026] The vehicle support plate 3 is further provided with a rotation stopping assembly 5.

[0027] The rotation stopping assembly 5 comprises a first rotation stopping groove 51, a rotation stopping block 52, a second rotation stopping groove 53, and a rotation stopping spring 54. The first rotation stopping groove 51 is arranged on the vehicle support plate 3, the rotation stopping block 52 is slidably arranged in the first rotation stopping groove 51, and the second rotation stopping groove 53 is arranged on the tire limiting plate 44. The first rotation stopping groove 51 communicates with the pushing groove 42 and the limiting groove 43. The rotation stopping spring 54 is arranged in the first rotation stopping groove 51 and can push one end of the rotation stopping block 52 into the second rotation stopping groove 53.

[0028] During the process of separating the vehicle support plate 3 from the lifting platform 21, the tire limiting plate 44 rotates, the first rotation stopping groove 51 and the second rotation stopping groove 53 communicate with each other, and then one end of the rotation stopping block 52 enters the second rotation stopping groove 53 under the action of the rotation stopping spring 54, thereby locking the tire limiting plate 44. When the car is loosened, the tire abuts against the tire limiting plate 44, thereby preventing the car from separating from the vehicle support plate 3.

[0029] The pushing block 41 has a pushing portion 55, which can push the rotation stopping block 52 to reset in the first rotation stopping groove 51.

[0030] During the process of putting the vehicle support plate 3 into the lifting platform 21, one end of the pushing part 55 will first enter the first rotation-stopping groove 51, push the rotation-stopping block 52 to move, and make the rotation-stopping block 52 enter the first rotation-stopping groove 51 as a whole. At this time, the tire limiting plate 44 will rotate, and with the pushing block 41 continuing to enter the pushing groove 42 and pushing the tire limiting plate 44 to rotate, the tire limiting plate 44 will enter the limiting groove 43, so as to make the surface of the vehicle support plate 3 flat, thereby facilitating the driving of the automobile.

[0031] The vehicle support plate 3 is provided with a leg support assembly 6, which comprises a fixed support leg 61 fixed on the vehicle support plate 3 and a movable support leg 62 rotatably arranged on the vehicle support plate 3. The fixed support leg 61 is in a fixed state and arranged on one side of the vehicle support plate 3. The movable support leg 62 is arranged on the other side of the vehicle support plate 3. The movable support leg 62 can rotate and is internally provided with a torsion spring, which is not shown in the figure. When the vehicle support plate 3 is separated from the lifting platform 21, the torsion spring can keep the movable support leg 62 vertically rotated. The vehicle support plate 3 is also provided with an abutting member for limiting the rotation of the movable support leg 62.

[0032] The abutting member comprises a first abutting block 63 arranged on the vehicle support plate 3 and a second abutting block 64 arranged on the movable support leg 62. The torsion spring pushes the movable support leg 62 to rotate, and at this time, the first abutting block 63 and the second abutting block 64 abut against each other. The leg support assembly 6 can facilitate the AGV transfer vehicle 11 to enter the lower part of the vehicle support plate 3 when the automobile is parked at a parking point, and the vehicle support plate 3 can be supported at the parking point. The existence of the leg support assembly 6 facilitates the AGV transfer vehicle 11 to enter the lower part of the vehicle support plate 3. When the movable support leg 62 needs to be folded, the movable support leg 62 is only needed to be abutted against one side of the lifting platform 21, and the lifting platform 21 can push the movable support leg 62 to make the movable support leg 62 fold.

[0033] The upper surface of the lifting platform 21 is fixedly provided with a displacement-preventing arc-shaped block 7, and the bottom of the vehicle support plate 3 is provided with a displacement-preventing arc-shaped groove 8 matched with the displacement-preventing arc-shaped block 7. The displacement-preventing arc-shaped block 7 and the displacement-preventing arc-shaped groove 8 can achieve the positioning effect of the lifting platform 21 and the vehicle support plate 3 and can prevent the mutual displacement of the lifting platform 21 and the vehicle support plate 3.

[0034] The AGV transfer vehicle 11 is provided with a plurality of lifting cylinders, the top of the lifting cylinder is fixedly provided with a positioning protrusion 9, and the bottom of the vehicle support plate 3 is provided with a positioning groove matched with the positioning protrusion 9. The AGV transfer vehicle 11 will transfer the vehicle together with the vehicle support plate 3 when transferring the vehicle, and at this time, the positioning protrusion 9 will enter the positioning groove, which can make the AGV transfer vehicle 11 more stable when transferring the vehicle support plate 3. The positioning groove is not shown in the application.

[0035] The implementation principle of the embodiment is that the lifting platform 21 rises to the ground, the vehicle support plate 3 is also on the ground, after the vehicle is driven onto the vehicle support plate 3, the lifting platform 21 is lowered, the AGV transfer vehicle 11 is located in the underground parking lot and directly below the vehicle support plate 3, as the lifting platform 21 is lowered, the lifting cylinder of the AGV transfer vehicle 11 is raised, and the positioning protrusion 9 enters the positioning groove. As the lifting platform 21 continues to descend, the pushing block 41 will leave the pushing groove 42, at this time, the tire limiting plate 44 in the tire limiting assembly 4 will be flipped and can limit the movement of the tire. The lifting platform 21 continues to descend, and because the AGV transfer vehicle 11 will push against the vehicle support plate 3, the vehicle support plate 3 no longer descends. When the pushing block 41 leaves the pushing groove 42, the lifting platform 21 is separated from the vehicle support plate 3. The AGV transfer vehicle 11 can transfer the automobile together with the vehicle support plate 3 to the parking point.

[0036] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application; therefore, according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the above specific embodiments and drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole of the present application or regarded as the limitation or restriction of the technical scheme of the present application. Therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
